I structured all my jobs to allow a quiet place to think and to take walks. Lived in California, Arizona, and Washington, all wonderful places to take walks.

Anecdata: I need fresh air and strongly prefer to keep windows open in most kinds of weather. My wife and my children, now all adults, picked up the habit. Our houses are usually kind of dusty.

I can confirm this, personally. Time and time again after struggling with a problem at my desk I get up and walk and the solution pops into my brain. Sometimes it's a long walk in the park and sometimes it's just going out to lunch, but it usually works. It doesn't really even have to be a walk, quite often the solution comes to me in the shower. I always chalked it up to not thinking about it and letting my brain figure it out. I guess I was right too.
